I would like to imagine the name resulted from some astronomer foreseeing how fun later generations would have with anus jokes. However, anuses apparently didn’t factor in, at least any more than they do into every other decision. This celestial body — initially called Georgium Sidus, “George’s star,” in honor of King George III — became Uranus when scientists generally agreed with the logic of astronomer Johann Elert Bode, who pointed out that because Jupiter’s father was Saturn, then this new planet should in turn be named for Saturn’s father. Grandpa, father, son — in order. Makes sense, I guess. But because some of the involved parties were English-speakers, and I presume they had anuses, I’d still like to think that at least some of them were in on the joke. They had to be, right?
A small post-script: My fifth-grade teacher insisted that the name of this planet was pronounced with the emphasis on the first syllable. Insisted. I cannot forgive her.
An additional post-script, added after the fact: The awkwardness of the name Uranus is totally compounded by the fact that the adjective Uranian was in the late nineteenth century used to mean “homosexual.” Oh, how the jokes write themselves.
